shape of the toe of the shoe, without disadvantageously affecting the smooth inner surface of the shoe insole, at least at the back of toe forepart of the insole where nearly all the pressure of the foot exists at the forepart of a shoe when in the act of walking or even of standing.

As shown in the accompanying drawings:

Figure 1 shows the underside plan view of the particular unchannelled ribbed insole for a welt shoe hereinbefore identified and the permanent reinforcing sewing rib fastening means that I have provided at the toe of the said insole;

Figure 2 shows the top plan view of the said unchannelled ribbed insole for a welt shoe and a cover that I have provided for the said permanent reinforcing sewing rib fastening means for the protection of the wearerrs foot; and

Figure 3 shows a cross-section taken on line 3--3, Fig. 1, of my improved unchannelled ribbed insole for a welt shoe.

Referring further to the drawings:

I have provided the unchannelled ribbed insole for a welt shoe l, which, preferably, is of leather, with the sewing rib 2, formed of cotton fabric, commonly known as gem-duckjhaving a reinforcing core 2', which may be of any suitable material, but, preferably, of the commercially well known insole material termed Onco, which is deemed by the applicant to be the best material for the purposevof reinforcing the sewing rib of the said insole, and an outer flange 3, and an inner flange 4which are disposed upon and secured to the underside peripheral margin ofthe body of the insolel, by the cementitious material 5, and I have provided at the toepart of the said insole permanent reinforcing sewing rib fastening means, preferably, in the form of a row of chain stitches 6, passing, preferably, through the outer flange 3, of the sewing rib, in close proximity to the sewing rib, and entirely through the body of the insole, leaving, invariably, the back of toe forepart of the insole free of such fastening means, and, as shown in Figs. 2 and 3, I have provided a cover 'l, which may be in any suitable form, but which, preferably, is, as herein shown, in the form of lubricating wax worked into the stitching seam by means of a hot iron, which is intended to protect the wearers foot from direct contact with the said stitching seam, and I have provided a reinforcing sewing rib fabric sheet 8, (such as shown in the aforesaid patent to Eno), and which forms an essential part of my invention in that both, the permanent reinforcing sewing rib fastening means, in the form of a row of stitches 6, provided by the applicant, and the said reinforcing sewing rib fabric sheet 8, form a novel combination co-operating in bringing about new beneficial results never before attained in securing the sewing rib to the body of the said insole. More specifically stated, the permanent reinforcing sewing fastening means, herein shown, perferably, in the form of a row of stitches 6, in being disposed upon the outer flange 3, of the sewing rib, hold the sewing rib fromY rearward movement on the body of the insole under the strain of the toe-wipers of the toe lasting machine upon the sewing rib, and the reinforcing sewing rib fabric sheet 8, in being disposed and secured to the body of the insole enclosed by the sewing rib and to the inner flange 4, of the sewing rib, cooperates with the said permanent reinforcing sewing rib fastening means in holding the sew- A further feature of my invention differentiating from the prior art, resides in invariably omitting the provision of permanent reinforcing sewing rib fastening means at the back'of toe forepart of the said insole leaving the surface of that part of the insole as smooth as that of a channelled insole for a welt shoe, and then without the objectionable gutter common with said channelled insoles along the line of the channel due to the pressure of the foot depressing that weakened portion of the insole, and notably so when said channelled insoles are incorporated in the medium grade of Goodyear welt shoes hereinbefore identified, embodying unchannelled ribbed insole for a welt shoe as shown in Figs. 3 and 4 of the aforesaid patent to Eno, and for which medium grade of shoes my hereinrshown improved unchannelled ribbed insole for a welt shoe is primarily intended.

I want it well understood that it is within the scope of my invention and of this application to provide reinforcing sewing rib fastening lmeans only around the toe-endV of the insole extending to an including the corners of the toe of the in.- sole, where maximum strength of the sewing rib is most needed due to the fact that the, toe-wipers of the toe lasting machine first engage the upper, the box-toe and the sewing rib atthe toeend of the insole and force that portion of the sewing rib in a heelward direction whilethe toewipers are lclosing in upon the upper. and the boxtoe at the sides of the toe of the insole; and to the further fact that the upper and the box-toe in being made to protrude atl the corners of the toe of the insole outwardly of the insole in the form of dog ears, so-called, under the influence of Y the pulling over operation at the toe of the upper,

ing rib from rearward movement on the body of inforcing sewing rib fastening means, only around the toe-end of the insole Yextending up to and including the corners of toe of the insole, is enough to bring about the desired beneficial results in holding the sewing rib situated at the toepart of the insole from disturbance on the lbody of the insole at the toe lasting machineroperation, ex?,

cept in special cases, as when thetoepart of the upper and/or the box-toe are extra heavy, or in the case of extra heavy shoes, such as workcshoes.

Furthermore, in providing permanent reinforc-A ing sewing rib fastening means, such as inithe form of a row of stitches disposed only around the toe-end ofthe insole extending up to and including the corners of toe of the insole, obviously would eliminate the need of a cover for the stitch-f ing seam at the top side plane face of the insole, and, even when the said row of stitches shouldextend to the side of the toe of the insole past the cor; ners of toe of the insole, such as herein shown, a cover may be omitted, depending, on whether or not-the material formingV the body of the insole is Y' of soft or firm texture; or whether or not waterf had been applied to the peripheral margin of the top side plane face'of the rm body of vtheinsole preparatory to the formation of the row of stitches on the insole to thereby soften the surface of the firm body of the insole to allow for the sinking in of the stitches below the surface of the body of the insole; or whether or not the stitching thread is of such tensile strength as to allow for the use of a size of thread small enough to avoid undue prominence of the stitches at the top side plane face of the insole.

Sumce it to say, that my invention and this application are intended to cover and do cover the various stated forms of the invention and that the claims, whenever the context so permits, are to be broadly and accordingly interpreted to give t0 my invention and this application al1 the protection to which I am entitled under the statutes.
